Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|

From your explanation I would conclude that all your primary particles pass through the aluminium slab but that they constitute only 56% of the flux; e.g. there are extra particles exiting the slab (as you would expect from hadronic and/or other interactions in the Al). The point is that the primary is not always 'killed' when it produces a secondary, though - and this I can't answer for certain - one might expect that the primary is 'killed' after an hadronic inelastic interactions.
However, there is an error in your logic; you want (for exiting):
charge2 = aStep->GetPostStepPoint()->GetCharge();
BTW, when you require:
if(volume == detector->GetScintillator_1() && point1->GetStepStatus() == fGeomBoundary)
where I presume point1 is aStep.GetPreStepPoint(), you are actually testing whether the track has just done its first step in GetScintillator_1; e.g. not when it arrives. For that you'd have to test both the status and the volume from point2 (of the previous step).
